What is CNC Turing?
It is a high precision machining method using computer control technology. CNC turning, also known as computer numerical control turning, is a machining process that utilizes computer control to rotate a workpiece while cutting tools remove material to obtain the desired shape. This method is suitable for manufacturing parts with complex geometrics, such as cylinders, cones and threads
The basic principles of CNC turning include the following key aspects: the workpiece is rotated on the lathe, the cutting tool is moved along a preset path, and the material is removed to form the desired shape and size. Through digital control instructions, the movement of the tool and the cutting speed can be precisely controlled, thus achieving high-precision and efficient production.
The Advantages of Cnc Turning Services
high accuracy and consistency, eliminating human error and ensuring that every component meets specifications
versatile and can be applied to a variety of materials and complex geometry
automation and computerized control increase production efficiency and speed, shorten delivery times, and improve customer satisfaction.
although the initial investment of CNC turning equipment is higher, its automation reduces labor costs, reduces material waste, and improves profitability.
Material used for cnc turned parts
The cnc turning process can be applied to a variety of materials, including Aluminum alloy, Stainless steel, Carbon steel, Tool steel, Titanium, Copper alloy, and Plastic.
CNC Turning applied industry
CNC turned parts is suitable for a number of industries including automotive, aerospace, medical, and electronics.
The latest cnc turning parts at SYM precision machining
Outer diameter machining
This is the most used machining method in CNC turning process, for the finishing of the beautifying surface and the rough cutting of the target shape at the initial stage of machining. During the outer diameter machining, the cutting tool contacts from the outside of the rotating material, and the chips sometimes wind around the cutting tool, and the tool Angle needs to be adjusted.
Inside diameter machining
During the inside diameter machining, the inside of a material is cut to enlarge the hole created in the material by opening the hole machining. The inner diameter machining needs to lengthen the tool according to the depth of the hole, but the long tool is prone to deviation.
Thread cutting
This is a machining method that produces pitch and can produce both external and internal threads. The use of special thread cutting tools for processing, we often using the “automatic feed function” to maintain a constant speed, so that the pitch is equal.
Cutting
- Cutting off unwanted parts by holding the tool against the material. Cutting requires the use of tools with thin blades.

Raw material selection
When selecting raw materials for CNC turning parts, consider the cost of materials, machinability, and material shape.
Dimensional accuracy and design
Using sectional tolerance to ensure accuracy in critical areas, design with two-end processing holes instead of deep hole processing if possible, design inner radii at the bottom of hole.
Thread design
Using standard thread profile, consider thread depth and thread relief.
Surface appearance requirements
CNC turning can achieve surface roughness values between Ra0.4 and Ra3.2. Set the roughness value based on required surface accuracy, keeping in mind that higher precision increases manufacturing costs. Consider laser lettering as a cost-effective alternative to engraving
By keeping these points in mind, designers can create CNC turning parts that are both functional and efficient to manufacture.
CNC milling services FAQs
Q1. How long can we receive quotation for cnc milling parts?
A:The quotation list for your cnc machining needs could be provided in 12 hours after receiving your RFQ.
Q2. What file need to be provided to evaluate the price of the machined parts?
A: We normally quote based on 2D drawing (.PDF|.JPG |.TIF |.PNG|.DWG), we can also quote the machined parts based on 3D drawing (.IGS | .SLDPRT | .STEP| .STP), and samples from you, you only need advise the material and key dimensions required.
Q3. Can you handle some post machining such as the heat treatment?
A: There are some post-machining services for metal machining parts. Through harden for some carbon steel machined parts, such as quenching, vacuum heat treatment. Caseharden for increasing the surface hardness of the metal parts.
Q4. What kind of surface finish for milled parts could you serve?
A: SYM can provide aluminum machined parts with any colors anodize, Trivalent Chromate Conversion, Nickel plating, Chrome plating, Black oxide, Zinc plating, E-coating, Pint, and Powder coating, etc.
Q5. Are you aware of the international regulations on machined parts?
A:Don’t worry, at SYM precision machining factory, all machined parts including the raw material and processes to comply with current ROHS directive, REACH regulations, and conflict minerals directive. The material certification and declaration of compliance to RHOS & REACH could be provided with shipment.
